Abstract:The development and on-orbit verification of the latest accurate attitude control 10 N rocket engine in China were introduced. The analysis of ground hot tests showed that the vacuum-specific impulse of the engine reached 295 s. The minimum impulse was better than 30 mN·s, with a minimum working pulse width of 6 ms, a cumulative ignition life of 68.7 h, and a cumulative pulse cycle life of more than 750 000. The engine’s reliability was fully verified and successfully demonstrated through the SJ-20 satellite in orbital tests. The development of this engine marked an essential milestone in the development history of high-performance bipropellant attitude control engines in China, indicating that the overall technology of the bipropellant attitude control engines in China has reached the advanced international level and generated extensive social and economic benefits.
